  • Publication number: 20230272682
    Abstract: A method for controlling drilling fluid properties includes receiving one or more measurements representing a drilling efficiency of a drilling rig including a drill bit deployed into a well. A drilling rig circulates a drilling fluid in the well. The method includes determining that the one or more measurements are lower than expected, determining that a property of a subterranean formation in which drill bit is positioned has changed based on one or more measurements, and in response to determining that the subterranean formation has changed, automatically generating a drilling fluid adjustment plan based at least in part on one or more of a drilling fluid inhibition factor or a drilling fluid stability factor.

    Abstract: Methods of performing a stimulation operation at a wellsite are disclosed. The wellsite is positioned about a subterranean formation having a wellbore therethrough and zones thereabout. The method involves establishing at least one objective for stimulating production of reservoir fluid from the subterranean formation and into the wellbore. The stimulating involves placing a stimulating fluid along the zones of the wellbore. The objective is based on wellsite data. The method also involves identifying at least one constraint for the stimulating, determining target distributions of the stimulation fluid based on the objective(s) and the constraint(s), and selecting operational parameters for the stimulating based on the constraint(s) and the target distributions. The method may also involve stimulating the subterranean formation using the target distributions and the operational parameters, monitoring the wellsite during the stimulating, and adjusting the stimulating based on the monitoring.

  • Publication number: 20190225876
    Abstract: Methods for treating subterranean wells in which the producing formation is a carbonate comprise preparing a treatment fluid comprising either: (a) an aqueous solution of a multivalent-cation reacting polymer; (b) a solution comprising a fatty acid and an ethanolamine; (c) an aqueous acidic solution of one or more compounds whose calcium salts are insoluble; or (d) an aqueous solution comprising urea or alkane derivatives thereof or both and polyvinylpyrrolidone (PVP). The treatment fluid is placed in the well such that the solution contacts the carbonate formation at a pressure lower than the fracturing pressure. The treatment fluid is allowed to react with the carbonate formation, thereby depositing a film onto the formation surface or part of the formation surface. Then an acid solution is placed in the well such that the acid contacts the carbonate formation at a pressure lower than the fracturing pressure.
